'FIREPROOF METAL WINDOW FRAME AND SASH- SPECIFICATION forming part of Letters Patent No. 770,571, dated September 20, 1904. Applicati fil d March 18, 1904.. Serial No. 198,746. (No niodel.)

To all whom it may concern:

Be it known that I, WAINWRIGHT B. GER- vA Is, a citizen of the United States of America,

and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fireproof Metal Window Frames and Sashes, of which the following is a specification.

The present invention relates to that class of window frames and sashes in which the sashes have horizontal pivotal connection to the frame and are adapted to swing in a vertical plane from an open to a closed condition or vice versa; and the object of the present improvement is to provide a simple, durable, and ecomical structural formation and combination of the window frame and sash parts adapted to afiord a very close joint between the sash and frame with but little incidental friction and to exclude the wind, rain, &c., in avery effective and perfect manner and which is capable of easy manipulation to pivotally open or close the sash in relation to the window-opening of the frame, all as will hereinafter more fully appear, and be more particularly pointed out in the claims.

In the accompanying drawings, illustrative of the present invention, Figure 1 is a vertical transverse sectional elevation at line w m, Fig. 2, of a fireproof metal window frame and sash embodying the present invention.

Fig. 2 is a front elevation of one side of the window frame and sash with a portion in section toillustrate the pivotal connection of the sash to the frame. Fig. 3 is an enlarged detail vertical transverse section at line 00 m, Fig. 2, illustrating the top portion of the frame and sash. Fig. 4 is a similar View illustrating the middle portion of said sash and frame. Fig. 5 is a similar view illustrating the bottom portion of the frame and sash. Fig. 6 is an enlarged detail horizontal section at line as :0, Figs. 1 and 2. Fig. 7 is a similar view at line 00 m Figs. 1, 2, and 8. Fig. 8 is an enlarged detail elevation of the pivot portion of the window-frame with the sash shown in dotted lines.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the lower horizontal member or sill of the window-frame, formed by a section of structuraliron right-angle bar, one web or flange of which depends vertically to rest upon or be embedded in the ordinary stone sill of the building, as circumstances may suggest.

2 is the upper horizontal member or lintel of the window-frame, formed by a section of structural-iron right-angle bar, one flange or web of which depends to form a shield or shed for the upper end of the opening of the window-frame. I

3 represents the vertical side members or jambs of the window-frame, formed by sections of structural-iron right-angle bars, having webs or flanges which project in a lateral direction from the window frame and are adapted to be built into the wall of the building to substantially and permanently secure the window-frame in place.

The aforesaid series of frame members 1, 2, and 3 will be connected together by riveting, welding, or other usual means to constitute a rectangular structure or frame having free inner edges.

4 represents the side rails, and 5 the top and bottom rails, of each window-sash, formed of structural-iron right-angle bars secured together in any usual manner to constitute a rectangular structure.

6 represents sheets of wire-glass, secured in said sash-frames by glazing or confining-strips 7, secured to one series of angle-webs of the series of sash-rails aforesaid and adapted to clamp the sheets of wire-glass 6 against the companion series of angle-webs of said sashrails, as shown, and where so desired putty flashings or other usual bedding means may be interposed between the surfaces of the glass sheets 6 and the webs and strips aforesaid to secure a wind and water tight joint between the parts.

8 represents pivot-bolts passing through the webs of the vertical right-angle iron side rails of the sash and screwing into the vertical side members or jambs 3 of the window-frame to afford pivotal connection and support for the sash in the window-frame. Such pivot-bolts will be usually arranged at the mid-height of the sash, as illustrated in Figs. 1 and 2, but may be arranged nearer the upper or lower ends of said sash, as circumstances may require or the judgment of the constructor may direct, and in the preferred form of the present construction, as shown in the drawings, such pivot-bolts will be arranged close to the window-glass 6, and the glazing-strips 7 will be cut away to permit of such arrangement, as illustrated in Fig. 1.

9 and 10 are upper and lower vertical receiving-pockets formed by sections of structural-iron channel-bars, having their basewebs extended laterally past the channels and secured to the vertical side members or jambs 3 of the window-frame, and with a view to permit of a pivotal swinging of the sash in a vertical plane upon the pivotbolts 8 such pockets are made of a vertical height something less than one-half the vertical height of the sash-frame, and the upper pocket will be located immediately outside the sash-frame, while the lower pocket will be located immediately inside the sash-frame, in the same manner as the outer and upper and the inner and lower stop-rails of the ordinary reversible window of the type in which the sashes swing in a vertical plane. A novel feature of this part of the present invention consists in eX- tending the inner portions 9 and 10 of the respective channel-bars 9 and 10 past each other, as illustrated in Figs. 1, 2, and 8, to constitute bearing or contact surfaces for the vertical end faces of the sash and avoid any gaps at such points through which the wind, &c., might freely enter.

l1 and 12 are respectively upper and lower transverse horizontal pockets formed by sections of structural-iron channel-bars having their base-webs extended laterally past the channels and secured, respectively, to the horizontal lintel member 2 and the horizontal sill member 1 of the window-frame and in ad ouble window-frame to an intermediate horizontal cross-rail, as hereinafter more fully set forth. Such horizontal pockets are arranged in respective alinement with the before-described vertical pockets 9 and 10, so as to constitute continuations of the same, as shown.

13 represents vertical tongues formed by sections of structural-iron right-angle bars secured to the vertical edges of the window-sash and having a vertical height equal to that of are adapted when the sash is in a closed position to occupy the vertical channels or grooves of the lower vertical pockets 1O aforesaid to afford a tight joint between the window sash and1 frame along the lower vertical half of the sas 15 is an upper horizontal tongue formed by a section of structural-iron right-angle bar secured to the upper horizontal edge of the sash and adapted when the sash is in a closed position to occupy the horizontal channel or groove of the upper horizontal pocket '11 aforesaid to afford a tight joint between the window sash and frame along the top edge of the sash.

16 is a lower horizontal tongue formed by the web of the right-angle iron horizontal lower rail 5 of the window-sash, and such tongue is adapted when the sash is in a closed position to occupy the horizontal channel or groove of the lower horizontal pocket 12 aforesaid to afford a tight joint between the window sash and. the frame along the lower edge of the sash.

17 represents elastic bearing-strips of'felt or other yielding material arranged in the various pockets 9, 10, 11, and 12 aforesaid and adapted to insure a more perfect joint between the window sash and frame.

18 is a transverse horizontal rail secured the mid-height of the window-frame and'which is employed in cases where a pair of sashes are arranged one above the other in a single window-frame. Such transverse rail in the present construction is adapted to carry on its upper surface one of the lower horizontal pockets 12 and on its under surface one of the upper horizontal pockets 11, located in the same relation as that heretofore described in connection with the pockets of the sill and lintel members of the window-frame.
